Abstract
Some illustrative embodiments of an instillation assembly for treating a tissue site may include a fluid distribution lumen and a fluid hub that may define a fluid instillation pathway. The fluid distribution lumen may be defined by a first film layer and a second film layer, and the fluid hub may be positioned in fluid communication with the fluid distribution lumen. The instillation assembly may be used in combination with a reduced-pressure assembly that may define a reduced-pressure pathway separate from the fluid instillation pathway.
Claims25
A treatment system for providing fluid instillation and reduced-pressure treatment at a tissue site, comprising:
- a plurality of fluid distribution lumens, each fluid distribution lumen being formed by a first film layer being sealingly coupled to a second film layer along a length and opposing sides, the opposing sides being positioned substantially normal to the length, each of the fluid distribution lumens having a delivery aperture;
- a fluid hub positioned in fluid communication with the plurality of fluid distribution lumens, the fluid hub extending outward from a surface of the second film layer, the fluid hub and the plurality of fluid distribution lumens defining a fluid instillation pathway;
- a plurality of leg members;
- a reduced-pressure hub in fluid communication with the plurality of leg members, the reduced-pressure hub and the plurality of leg members defining a reduced-pressure pathway separate from the fluid instillation pathway;
- a fluid supply lumen adapted to be coupled in fluid communication with the fluid hub;
- and
- a reduced-pressure lumen adapted to be coupled in fluid communication with the reduced-pressure hub.
